Laser traveler trailer

Hi I'm looking to purchase new laser trailer, perhaps A frame, in Midwest area. I have looked at Load Rite , Genesis Trailers, Karavan, etc.
I like Dynamic Dolly Combo Trailers.

Can anyone recommend what trailer should I purchase.? Is aluminum better the galvanized ? What frame should i purchase because i'm planning to purchase dynamic dolly rack for two laser boats to i can take two laser to master events.
I'm in Illinois , Chicagoland area, willing to...
